If you look up “Four 4s Challenge” on yt you should find a couple videos explaining it! i just watched a little bit of one so i’ll try and help now though.
I’ll do 1-5 for you and try my best to explain :)) and if you need more answers or more help just let me know
So first, we need to find out how to get 1 using four 4s
1. (4/4)/(4/4)
this would read “four divided by four divided by four divided by four” which equals 1
2. 4/4+4/4
3. (4+4+4)/4
4. 4*(4-4)+4
5. (4*4+4)/4
Remember that you’ve gotta use an equation with just four 4s to get to every number
